Abstract
A method and apparatus for providing a clean working area within an enclosure while simultaneously permitting open access to the working area from outside and also preventing any toxic substances from escaping the enclosure to contaminate a worker area. A higher pressure region within the enclosure near the aperture of the enclosure prevents dirt from entering and toxic materials from escaping.
